This template tag will categorise tagged articles into Category:Articles that may contain original research. This template is a self-reference and so is part of the Wikipedia project rather than the encyclopaedic content.
The intention of this tag is to nudge fellow editors who may unknowingly (or otherwise) introduce material based upon original research into supporting such material through demonstrating its origins. This tag provides a good faith means for editors to allow given text of fellow editors to remain temporarily in a given article until such time as the text's origins are supported.
In the event that the source of the material is not provided after a reasonable period of time, the tagging editor would generally be right in assuming that it could be edited or completely removed from the article to comply with policy.
When adding this template to an article, you should also specify your concerns on the article's talk page.
Usage[change source]
If an article contains many statements of questionable origin that you suspect is original research, add the following to the top of the article: ((original research|date=June 2024))
If the problem is only relevant to a particular section, place the tag at the top of that section instead, adding |section to the markup.
If the original research only relates to a few statements, consider using the inline variant ((or)) instead. Simply tack on ((or|date=June 2024)) to specify that particular passage as likely being of questionable origin.
Do not use this tag to label text which appears false or doubtful, especially in the case of biographies of living people. In the case of text that appears false or doubtful and is not part of a biography of a living person then move such text to the discussion page and ask for citations of previous research there, otherwise remove it.
